Member Oct 26, 2017 854 Kansas, U.S. Has anyone got a "Invalid Format" error from the Xbox Series X on a LG OLED when playing games or watching videos from the Xbox Series X? I have been getting these errors recently. Has anyone else got these errors as well?

Are you using the HDMI cable that came with your Xbox?

Yes, I ordered a new HDMI cable to see if it fixes the issue.

There's one annoying issue with my CX though, sometimes when I'm watching Netflix it will randomly switch to the last used HDMI input even though no device has been turned on, it's fucking annoying and afaik it only happens with Netflix for now. Maybe I should reinstall the app.

Member Oct 25, 2017 18,817 It's true that HDMI 2.1 cables are way more fickle than previous versions. A lot of the early ones just don't reliably do 4K 120hz because they came out before anything actually was able to output in 4K 120hz. They weren't properly tested for it, because they really couldn't be. Go either Monoprice or at least make sure to get a certified 2.1 cable from Amazon like this one: https://www.amazon.com/dp/B0919GTQS9/

Member Oct 27, 2017 37,896 I never had this issue AFAIK, and I dont know if it has to do with Atmos, but I had to do some research on AV forums for how to even enable Atmos on an LG CX This could be related to sound or the HDMI cable, input.

Member Oct 27, 2017 8,240 Sometimes when I turn on the console before swapping inputs I get that error. A couple of times the console has reverted to 640x480 output. Restarting the console fixes it. I haven't had it when swapping games or during gameplay. Just when turning the console on. I use power saving mode.

Verified Oct 27, 2017 8,829 California I have had this issue. I sent my SX in, and they reset everything, and it still happened. What changed it for me was a new C1. I had a blue vertical line showing on my C1, so I had to exchange it. Once I got my new C1, I have not had this problem. I got the TV when it was first released. My new C1 has a build date of November 21. The main problem is a faulty handshake somewhere. I changed cables, only to be left with the same issue. The flickering in my case was 100% of the time, and occasionally, I'll receive an "Unsupported Format" message from my panel when watching YouTube TV or YouTube. When this message was seen, I had to turn off the TV or console. Here is what I think is happening. I believe there is an EDID read failure happening from the OS side. I believe it is an EDID read failure due to circumstances that follow the failure. For instance, when the failure occurs, often, the console will fall back to 640x480. From my experience, this is due to the OS failing to read the EDID correctly, and the GPU resorts to 640x480 to project an image despite the read failure. Also, when this failure happens, you cannot change the resolution, which indicates a read failure. In the image below, none of the 4k settings are checked in the console's menu, so this could mean that none of the panel's information was passed to the console to set the modes correctly. If settings aren't displayed correctly, that means the system could not read the EDID to know what settings it supports. Since I changed C1's, I have not had an issue. I'm using the same cable setup that was initially failing. I'm not entirely sure what changes, if any, went into the new C1's. I'm sure they are using the same TCON, but some slight modifications could have happened. Last edited: Dec 13, 2021 You must log in or register to reply here.
